IMO, the C19 and the Sunfire Classic are both very good. The C-19 has a lot of extra's that can allow you to change the sound to meet the demands of the room. The Sunfire was ment to be flat and has very little in tone control.

If you really want your C19 to kick some but, contact beemers417 at www.vintagehifishop.com. He does a great upgrade to the C19. There are several memebers on this forum who have had the upgrades done and they love it.
